The present invention relates generally to an information retrieval/information retrieval result providing system and an information retrieval/information retrieval result providing method and a storage medium recording method program. More particularly, the invention relates to a system, a method and a storage medium recognizing a search request item of user, a search level, an information retrieval result providing method, a search range, an information storage period, an information access terminal and information storage site, performing information retrieval from an information sending server presenting on a network, such as internet or the like, processing the information retrieval result, storing for a given period and providing information retrieval result to the user.

2. Description of the Related Art

Conventionally, as an information retrieval method and an information retrieval result providing method for retrieving and providing information presented on the network, utilizing network on the internet, there has been known a providing method of performing retrieval (searching) information on the information sending server on the network by information retrieval server depending upon a demand of information retrieval for the predetermined information retrieval server from the user and transmitting the information retrieval result at a timing where information retrieval is performed. Here, the information retrieval server provides URL (Uniform Resource Locator) of the information sending server presenting the information matching with the retrieval item demanded by the user, and summary (information summary) of information, as information retrieval result.

FIG. 11 is an illustration showing the conventional information retrieval system and information retrieval result providing method. The conventional information retrieval system and the information retrieval result providing method are constructed with a user terminal 210, an information sending server (1) 230, an information sending server (2) 231, an information sending server (3) 232 established and managed by business entities, organizations, individuals for the purpose of presenting information, an information retrieval server (1) 220 and an information retrieval server (2) 221 established and managed by business entities and organizations for the purpose of retrieval of information presented on the network, and a network 200 connecting respective components with each other.

The user accesses the information retrieval server (1) 220 or information retrieval server (2) 221 via the user terminal 210. Here, it is assumed that the user selects the information retrieval server (1) 220 as the information retrieval server to request information retrieval. The user designates keyword, term or the like of the information retrieval item on a display screen of the user terminal 210. The designated keyword or the like is transmitted (201) to the information retrieval server (1) 220 via the network 200.

The information retrieval server (1) 220 receiving the information retrieval request recognizes keyword, term and so forth input by the user to the user terminal 210 to perform collection of information from the information sending server (1) 230, the information sending server (2) 231 and information sending server (3) 232 established on the network.

The information retrieval server (1) 220 recognizes presence of information containing the keyword designated by user in the information sending server (1) 230 and the information sending server (2) 231 and obtains (202, 203) of URL and information summary of the information sending server (1) 230 and the information sending server (2) 231.

The information retrieval server (1) 220 completed collection of information transmits (205) information retrieval/collection result to the user terminal 210. Then, the user obtains and accesses demanded information via the user terminal 210.

In the conventional information retrieval system, depending upon mechanism of web browser used for accessing information retrieval demand and information retrieval result, the information retrieval server merely provides the information retrieval result by temporarily displaying the Web browser and is designed to perform process of providing the information retrieval demand and the information retrieval result by synchronizing (mutually transmitting and receiving data) the user terminal and the information retrieval server. Accordingly, in the conventional information retrieval and providing method, when the user requires information once retrieved in the past, information retrieval has to be newly performed to repeat operation of process procedure for obtaining retrieval information to be impossible to effectively use the information result, such as transfer of the retrieved information to the other party.

On the other hand, since the conventional information retrieval system is designed to constantly provide information retrieval result from the information retrieval server in response to the demand of the retrieval information from the user, the user is required access period due to retrieval period every time in repeated access to the information retrieval result, and is also required access period depending upon the location of the user terminal due to distance and crowded condition to the information retrieval server on the network.

Furthermore, in the conventional information retrieval system, a method to display only URL of the retrieval result and summary of information to be presented the URL has been taken. When broadband image information, audio information, special format data and so forth are present in the URL, checking and access of such data is impossible unless the user terminal has a function for reproducing such data. Namely, in diversification of functions of the user terminals, most of users cannot access the information retrieval result equally.

On the other hand, in the conventional information retrieving system, the information retrieval server takes all information sending server established on the network. Therefore, when huge amount of information retrieval results are presented, user has to spend large amount of time for obtaining truly required information. For example, when several hundreds of relevant URLs are obtained as a result of the retrieving on the network by the information retrieval server, the user has to perform troublesome checking process in order to narrow down to necessary minimum number of URLs containing required information out of several hundreds of URLs.

In the conventional information retrieval system, access method only by the Web browser is employed to operate the user terminal and the information retrieval server in synchronous manner while the information retrieval result is accessed and displayed by the Web browser. Then, the user terminal is in the state where retrieval and information access are active, the user is not possible to even store the information retrieval result from the user terminal to other server or so forth.

(Discussion for Operation)

Next, concerning operation of the first embodiment, discussion will be given with reference to FIGS. 1 to 5 and 10.

At first, a procedure upon demanding information retrieval through operation of the user terminal by the user will be discussed.

FIG. 2 is an illustration showing a process flow in the case where the user demands information retrieval, and FIG. 3 is an illustration showing an example of an information retrieval register screen displayed on the user terminal.

The user accesses the information retrieval server 20 of the information center 40 established on the network (internet) 100 via the user terminal 10 (step A1). The information center 40 recognizes the access demand from the user terminal 10 and transmits data of an information retrieval registration and login screen to the user terminal 10 (step A2). The user terminal 10 receives the data and displays the information retrieval registration and login screen on a display screen (step A3). On the user terminal 10, an information retrieval registration screen example 50 shown in FIG. 3 is displayed. The user performs declaring and registration to necessary portions observing the information retrieval registration screen example 50.

The user inputs a keyword for information retrieval or explanation relating to the information desired to collect in the information collection request item column 51. Furthermore, the user considers how to effectively use the information retrieval result later to select level from selection items in the search level column 52, such as a declared level, URL level and summary of respective URLs, and only URL level collecting only URL. Furthermore, the user selects desired file format to be presented the information retrieval result, into which the staff assigned to the information retrieval server 20 or the information center 40 edits the result of information retrieval and collection, in an information retrieval result providing format column 53. Also, the user designates a search range for information retrieval in the search range column 54. Furthermore, the user designates a search data up to reception of information retrieval completion notice in a search data column 55. Furthermore, when the information retrieval result is required to be stored temporarily, the user can designate a storage period in the information storage period column 56. Also, the user designates a terminal which is intended to access the information retrieval result in an information accessing terminal column 57. The information retrieval server uses the designated information of the information accessing terminal to customize the present of the information retrieval result.

Also, the user is required to set own name of the user, a card company in contract and credit card number in a credit card number column 58. Designation of individual name, the card company and card number are used for user authentication and accounting process of the information retrieval server 20 and the information storage server 21. Finally, the user registers own electronic mail address 59. The electronic mail address is used for notification of a user ID and password from the information retrieval server, notification of completion of information retrieval, and distribution of information retrieval result through electronic mail.

The user inputs necessary information to the information retrieval registration screen example 50 to transmit the input information to the information retrieval server 20 via the user terminal 10 to log-in the information retrieval server (step A4). The user may log-out after completion of registration of information retrieval to the information retrieval server (step A5). Then, the information retrieval server 20 cuts off the log-in session to the user (step A6).

Next, the information retrieval server 20 recognizes and verifies information in the information retrieval registration screen example 50 transmitted via the user terminal 10 to issue the user ID and password to the registered user (step A7). Here, user ID and password notifying means (step A20) for notifying the user ID and password to the user from the information retrieval server 20 notifies then by the electronic mail. By notification by the electronic mail, the user, the user terminal 10 and the information retrieval server 20 become asynchronous relationship. The user may check the user ID and password notified by the electronic mail from the information retrieval server 20 at different timing or occasion.

Also, the information retrieval server 20 make reference to the keyword and search range 54 in the information collection request item column 51 designated by the user to perform information retrieval (search) for the information sending server (1) 30, the information sending server (2) 31 and information sending server (3) 32 established on the network 100 (step A8). After information retrieval (step A8), the information retrieval server 20 performs an information retrieval result editing process (step A9) with making reference to the search level designated by the user in the search level column 52, information retrieval result providing format set in the information retrieval result providing format column 53 and the information accessing terminal designated in the information accessing terminal column 57. The information retrieval result editing process (step A9) performs automatic process in the information retrieval server 20 and performs process by the staff assigned in the information center 40, if required. On the other hand, after the information retrieval result editing process (step A9), the information retrieval result is stored and maintained in the information storage server (1) 21 in the information center 40.

Next, the information retrieval server 20 performs accounting process for the user (step A10). In the accounting process (step A10) of the information retrieval server 20, reference is made to the accounting method table to estimate account for the user. Concerning request for information retrieval from the user, the information retrieval server 20 make reference to the information of an accounting method table 80 for determining up and down of the account (cost) 81.

FIG. 10 is an illustration showing a content of description in one example of the accounting method table 80. The accounting method table 80 is consisted of a search period 82 for information retrieval, a search result information amount 83, a search technical item 84, a search area 85, a search result edition (manpower) 86, a attached file (reference file) 87 held by the information retrieval result, a search result edition (expertise) 88, a search result storage period 89 and a search storage position 90. In each accounting factor (which generally refer the elements 82 to 90 of FIG. 10), a particular value is set.

When the accounting process (step A10) is completed, the information retrieval server 20 issues the information retrieval completion notice to the user (step A11). Here, information retrieval completion notifying means (step A11) for providing the notice to the user from the information retrieval server 20 is the notice by the electronic mail. By notice with the electronic mail, the user, the user terminal 10 and the information retrieval server 20 becomes asynchronous relationship. The user may check completion of information retrieval notified by the electronic mail at different timing or occasion.

Next, discussion will be given for process procedure (step) upon accessing the information retrieval result by operation of the user terminal by the user.

FIG. 4 is an illustration showing a process flow of the case where the user accesses the information retrieval result, and FIG. 5 is an illustration showing an example of information retrieval result obtaining screen displayed on the user terminal.

For accessing the information retrieval result, the user accesses to the information retrieval server 20 of the information center 40 established on the network (internet) 100 (step B1). The information center 40 recognizes access demand from the user terminal 10 to transmit the display data of the information retrieval result obtaining screen for the user terminal 10 (step B2). The user terminal 10 receives the display data to display the information retrieval result obtaining screen on the screen (step B3). Then, the information retrieval result obtaining screen example 60 shown in FIG. 5 is displayed in the user terminal 10. The user sets and registers items required to be fill in the setting or writing column in the information retrieval result obtaining screen example 60.

On the information retrieval result obtaining screen example 60, the user ID and the password notified from the information retrieval server upon demanding information retrieval (steps A7 and A20 in FIG. 2) are set in a user ID column 61 and a password column 62 and selects either displaying of information retrieval result access and transmission column 63 or request for delivery by a medium. When the request for delivery with the medium is selected, the information retrieval result which has been present only in the information storage server 21 on the network, can be maintained on the user's hand for effective use. Furthermore, the user may request updating of the storage period in a storage period updating column 64 of the information retrieval result with anticipation of making reference of the information retrieval result again.

Next, the user transmits setting and registration information of the information retrieval result obtaining screen example 60 to log-in the information retrieval server 20 and the information storage server (1) 21 (step B4). The information retrieval server 20 and the information storage server (1) 21 perform user authentication with reference to the transmitted user ID and the password (step B5). Next, the information retrieval server 20 checks the information retrieval result access and transmission column 63 and the information retrieval result storage period updating column 64 designated by the user through the information retrieval result obtaining screen example 60 (step B6). The information retrieval server transmits the information retrieval result to the user terminal and transmits the accounting information (step B7). The user checks access of the information retrieval result and account through the user terminal 10 (step B8). The user notifies completion after accessing of the information retrieval result to the information retrieval server and then logs-out (step B9). The information retrieval server 20 and the information storage server (1) 21 of the information center 40 cut off the login session with the user (step B10).

The information retrieval server 20 performs a process of the information retrieval result demanded by the user according to the content of the checking of the retrieval result transmission (step B6) (step B20). When the user demands variation of the storage period of the information retrieval result, the information retrieval server 20 performs information retrieval result storage period updating process (step B11). On the other hand, when the user demands deletion of the information retrieval result, the information retrieval server 20 deletes the information retrieval result from the information storage server (step B12). When the user demands media transmission of the information retrieval result, the information retrieval server 20 performs process corresponding to demanded medium (step B14). When the demanded medium is electronic mail, the information retrieval server 20 sends the electronic mail to the electronic mail address of the user (step B21). When the demanded medium is paper, facsimile or CD-ROM, the demanded medium is mailed the demanded medium, i.e. paper or CD-ROM by ordinary mail to the user or transmitted via facsimile. In the alternative, data may be directly transmitted to the user (step B22 and B13).

With the first embodiment set forth above, by installation of the information storage server and declaring of the information storage period, the user is not required to repeat new retrieval when the same information once retrieved is accessed. Namely, it becomes unnecessary to access the information retrieval result from synchronous operation accompanying retrieval operation of the information retrieval server, constantly. Furthermore, by declaring of the search level, necessary minimum information retrieval result can be obtained. Furthermore, by declaring the information retrieval result providing format and declaring access format, such as medium transmission or the like, the information retrieval result can be obtained as format useful for the user to reduce wasting in use of the information retrieval result. Also, upon accessing of the information retrieval result, it becomes unnecessary to care about function of the terminal owned by the user. On the other hand, the user may obtain the information retrieval result as physical medium and thus can effectively use the information retrieval result.

Accordingly, in the circumstance where the information sending servers are shooting up on the network, the user may efficiently perform information collection to have a room to establish a business between the information retrieval server and the information storage server.
